| Abstract: | Through systematic observation of temperature of greenhouse vegetables,we established the regression models about the lowest temperature inside and outside greenhouse under different weather conditions, ascertained the weather forecast index for freeze injury to greenhouse vegetables by low temperature, analyzed the characteristics of time distribution of freeze injury by low temperature to greenhouse vegetables in Guanzhong area by taking Jingyang for example, and then put forward countermeasures for prevention of different grades of freeze injury by low temperature. |

| Keywords: | Guanzhong area of Shaanxi greenhouse vegetable freeze injury index prevention measure |
